Bently Nevada 3500/45 176449-04+135137-01 Position Monitor
Manufacturer: Bently Nevada
Product Number: 3500/45 (176449-04 + 135137-01)
Category: Position Monitor
Number of Channels: 4
Application: Accurate measurement and protection for rotating machinery such as turbines, compressors, pumps, and motors
Product Description
The Bently Nevada 3500/45 Position Monitor (176449-04 + 135137-01) is a four-channel module designed to provide accurate measurement and protection for rotating machinery such as turbines, compressors, pumps, and motors.
This module continuously monitors shaft position, axial thrust movement, and dynamic vibration using Proximitor® proximity probes or compatible eddy-current displacement sensors. It separates the incoming signal into static (DC) and dynamic (AC) components — where the DC value represents the average shaft position or thrust wear, and the AC value represents shaft vibration.
The module works as part of the Bently Nevada 3500 Machinery Protection System, which is one of the most widely used platforms for condition monitoring and machine protection in industrial environments.
The 176449-04 represents the rear I/O module, while the 135137-01 refers to the front monitor module. Together, they form a complete, fully functional 3500/45 monitoring unit.
Key Features
-
Four fully independent measurement channels.
-
Compatible with Proximitor® probes and eddy-current sensors.
-
Measures both static (position) and dynamic (vibration) components.
-
Configurable Alert and Danger thresholds per channel.
-
Provides 4–20 mA, relay, and system bus outputs.
-
Advanced digital signal filtering for noise reduction and accuracy.
-
Hot-swappable design for simplified maintenance.
-
Seamless integration with other Bently Nevada 3500 modules.
-
High reliability for continuous, 24/7 online monitoring.
